Effects & uses

People most often describe Grapefruit as happy and uplifting, with a euphoric lift and a noticeably energetic edge rather than a heavy or sedating feel. It tends to stand out for focus, so users often reach for it during the day when they want to stay clear and on task. It is less often chosen for creative work, where some find it doesn't spark much in the way of new ideas.

The aroma and flavor lean toward bright citrus with a sweet finish. Lab tests show myrcene as the dominant terpene, followed by caryophyllene, with smaller amounts of alpha-pinene and humulene. THC typically lands around 19%.
